Siemens EE3A100L: 3-Pole 480V Bolt-On Circuit Breaker

The Siemens EE3A100L is a purpose-built 3-pole circuit breaker designed to protect three-phase power systems at a 480V rating. This bolt-on variant is optimized for installations that require a secure, field-serviceable mounting solution and precise compatibility with Siemens panels and equipment.

• Three-pole protection for balanced 3-phase circuits. Ideal for industrial environments where reliable phase protection is essential.
• 480V voltage rating. Suitable for higher-voltage distribution and equipment that operates on three-phase power.
• Bolt-On mounting design. Facilitates secure attachment and straightforward replacement in compatible panel setups.
• Exact compatibility reference. The part number EE3A100L is the most reliable reference to ensure a correct match for your installation.
• Maintenance, retrofit, and replacement use. A practical choice when upgrading or restoring existing systems that require matching specifications.
• Compatibility discipline. Before ordering, confirm fit and ratings align with your panel and application to avoid mismatches.

Use cases and ideal applications

This breaker is well-suited for facilities and projects that rely on Siemens electrical infrastructure. Use it for:

• Maintaining existing Siemens panel fleets where a bolt-on, 3-pole, 480V solution is required.
• Retrofits or upgrades of aging equipment that demand precise part-number compatibility (EE3A100L).
• Replacement of failed breakers in 3-phase distribution networks that operate at 480V.

Why choose the EE3A100L for your system?

Choosing a breaker by exact part number minimizes risk and downtime. The EE3A100L ensures:

• Accurate alignment with your Siemens panel design and interface requirements.
• Consistent electrical protection across all three phases, preserving system balance and safety.
• Simplified procurement logic—rely on the EE3A100L as the definitive reference for compatibility.

Practical guidelines for ordering and installation

To ensure a smooth fit and reliable performance, verify the following before purchase:

• The application uses a 3-pole configuration compatible with bolt-on mounting.
• Your system operates at or near a 480V three-phase distribution level.
• The installation panel accepts bolt-on breakers and matches Siemens’ hardware interface for EE3A100L.
• You reference the EE3A100L part number to confirm совпадение with existing inventory and schematics.
